Real world gains from increase tire pressure to max

[guest001]

I'm looking for real world data on just increasing your tire pressure and not doing anything else different mpg gains?

I'm considering doing this as the tires on my car have a patch and are old as hell anyway and have probably been needed to be replaced.

You can measure your own real world data.
